CVE-2022-45146 is a medium-severity vulnerability affecting the FIPS Java API of Bouncy Castle, specifically versions before 1.0.2.4. This vulnerability arises from changes to the JVM garbage collector in Java 13 and later, which can cause temporary keys used by the BC-FJA FIPS modules to be inadvertently zeroed out while still in use. This situation could lead to errors or potential information loss. It is important to note that FIPS compliant users remain unaffected, as the FIPS certification only applies to Java versions 7, 8, and 11.
The CVSS score for this vulnerability is 5.5, indicating a medium severity level. The potential risk to organizations includes the loss of sensitive information, which could affect system integrity and customer trust. Given the nature of the vulnerability and the potential for exploitation, organizations should prioritize addressing this issue in their patch management processes.
Currently, there is no known public exploit for CVE-2022-45146, and it has not been included in the Known Exploited Vulnerabilities (KEV) catalog. Nonetheless, organizations should remain vigilant and monitor for any updates or advisories related to this vulnerability.
Given the medium severity of this vulnerability, organizations should address it in their priority patch cycle to mitigate potential risks.
Vulnerability Details
CVE-2022-45146 was published on November 21, 2022. The vulnerability is classified under CWE-416, which refers to the use of a potentially dangerous state (in this case, zeroed-out temporary keys). The vulnerability primarily impacts the Bouncy Castle FIPS Java API component, which is crucial for cryptographic operations in Java applications.
Organizations using Bouncy Castle FIPS Java API versions prior to 1.0.2.4 should consider upgrading to the latest version to avoid potential risks associated with this vulnerability.
Technical Analysis
The root cause of this vulnerability lies in the changes introduced in the JVM garbage collector in Java 13 and later. These changes can lead to a situation where temporary keys used by the BC-FJA FIPS modules are zeroed out while still in use, creating a risk of errors or information loss. This vulnerability is categorized as having a low attack complexity and requires low privileges for exploitation. No user interaction is necessary, which increases the potential risk for affected systems.
The confidentiality impact of this vulnerability is high, as it can lead to unauthorized access to sensitive information. However, the integrity and availability impacts are assessed as none, indicating that the primary concern relates to the potential exposure of confidential data.
Risk & Impact Analysis
Organizations using the affected FIPS Java API may face significant risks, especially if they operate in sensitive environments where cryptographic operations are crucial. The potential for information loss can have far-reaching implications, including non-compliance with regulatory standards and loss of customer trust.
With a CVSS score of 5.5, this vulnerability falls into the medium severity category, indicating that it should be addressed in a timely manner but does not require immediate remediation actions. Organizations should assess their exposure and prioritize their remediation efforts accordingly.
The lack of known exploits and its non-inclusion in the KEV catalog suggests that while this vulnerability is serious, it may not currently be a top priority for threat actors. However, organizations should remain proactive in their defense strategies.
